T0 all whom it 'may concern:

Be it known that I, PAUL MAUsnr., of OberndOrfbn-the-Necliar, intheKingdom of Viirternberg, German Empire,have invented an lmprovement inRepeating Fire-Arms, of which the following is a full and clearspecification.

The invention relates to that class of guns which are closed by acylindrical breech-piece whose locking and firing mechanism is knownunder the name Mauser,77 and in which the eartridge-holdin g magazine issituated beneath and along the barrel.

The object of the invention is to furnish a device by the application ofwhich to guns of the mentioned pattern these guns may be used at willeither as repeating or as single-shot arms.

In the accompanying drawings, in which similar letters indicate likeparts, Figures 1 to 8 represent a new gun constructed according to thepresent invention; Figs. 9 to 12, a modification of certain parts, andFigs. 13 and 11 show the application of the invention to an old gun ofthe so-calle( pattern 71.77 Fig. 1 is a longitudinal vertical section,the breech closed, Fig. 2, partly the same section, partly a side view,the breech opened; Fig. 3, a horizontal section from below, in the lineA B C I) E ofFig. 1. Figs. 4, 5, 6 are cross-sections in the lines F G HI K L of Fig. 3. Fig. 7 is an elevation of the left side, partlyinsection; Fig. 8, a horizontal longitudinal section ofthe extractor.Figs. 9, 10, 11, 12 show sections and views of some ofthe improved partsconstructed differently from the same parts in the previous figures.Fig. 13 is a horizontal longitudinal section of a gun of the pattern 71,altered according to the present invention and with open breech; Fig.14, a vertical crosssection in the line M N of Fig. 13.

The main feature of the improved arm is a cartridge-carrier, b,oscillating on its rear end and brought in action, when wanted, by themovements of the breech-piece or lock f. This carrier b. when standingin a downward inclined position, receives the cartridge c from themagazine arranged beneath and along the barrel, and delivers it to thebarrel when lifted in an upward inclined position. The earrier Z) islifted and depressed by the movement of the lockf, the front end ofwhich serves as a breech-block, and which contains and coinmands theringbolt. During thelifting motion of the carrier the next cartridge aof the magazine is stopped and retained by a tailpiece, h, of thecarrier b. When the carrier b occupies its lowest position thiscartridge is impelled by the driving-spring of the 1nagazine up into thescooped-out bed of the carrier b. The following cartridge is stopped bythe projection d of a spring, e. Vhen the carrier Z1 is lifted itpresses back the spring c by means of its swell m and liberates thecartridge, a1- lowing it to move to the tail-piece 71, which stops itagain until the next depression of the carrier b.

On the rear of the carrier bis mounted a block, z', sliding up and downin a dovetailed groove of the carrier. Then the block t' is in itshighest position its top portion, 7.', is rocked to and fro by shouldersor projections p and q of the extract-or o, which latter is fixed to thelock f and moves with it. This rocking ino tion causes the front end ofthe carrier I) to rise when the lock f is moved backward and the breechopened, and to fall when the loekf is moved forward and the breechclosed. rIhe extractor o is not integral with the loekf, although it isattached to and moves with it.

-Being made separate, it is capable of removal and replacement, and whenworn or injured it may be removed. Vhen the sliding block z isdepressed, so that its top, 7.", is out ofreaeh of the shoulders p g,the carrier I) will not be moved*that is to say, the repeater isconverted into a single-shot gun. It is important to stop the movementof the carrier b whenit is raised, forming in this position a smoothbottom in the chamber c best adapted to introduce into the barrel acartridge when loading by hand. To accomplish these objects the slidingblock z' is depressed by a pin, c, on the end of the shorter arm of abell-crank lever, s, swinging round the screw-pin t. The longer arm ofthe bell-crank lever protrudes on the side of t-he chamber c, and isshifted into the scribed already above.

. which turn on the screw-threaded end.

2 esente required position by hand by means of the thumb-piece a of thearm s. The pinvworks in a horizontal slot of the slide-block t'. Theshifting of the levei1 s, and thereby the depressing of t, is performedwhen the carrier b is in its highest position, when the block is drawnback for loading. rlhe sliding block i rests in its lowest position withits lower back edge against an offset, x, provided on the inside of thechamber or case c, so as to iixthe carrier Z) in its elevated position,prohibiting1 its being depressed until the sliding block t is again"raised, liberating at once the carrier b and transforming thesingle-shot gun again into a repeater.

The spring e is furnished beside the swell m in the front end with asecond similar swell, n, on

the back end. rlhe latter exerts a uniform spring-pressure against thecarrier b at its fulcrum g, while the swellm performsthesame duty assoon as the front end of the carrier b has left its lowest position. Bythis arrangement the movement of the carrier b is made smooth and easy.To show that, and also how the construction of the details can bealtered without leaving the ground of the invention, a modification ofthose parts which control the movements of the carrier b is shown inFigs. 9 to 12. The slide-block is not guided by a dovetailed grooveofthe carrier l), but by a square one, and it is moved up and down notby a pin, but by the direct contact of the shorter arm t of thebell-crank lever. rIhis arm c works in a suitably-shaped recess of theblock t', and swings, together with the longer arm s, around thescrew-bolt g t, by means of which and of the coupled hubs g of the twolevers c and s, these latter are united to a solid piece. The arm cworkson the left side of the gun, while the arm s protrudes on the rightside, so that it can be moved to and fro by means of its thumb-piece u.In this way the slide-block il is moved up and down, presenting its topk to the shoulders l) and q of the extractor o, or bringing it out ofreach of them, exactly as it is derlhe carrier b swings here notdirectly round the screw-threaded end, but round the hubs g t of thelever c s, rIhc recess of the block 13 is large enough to clear the hubsg in any position. By this construc- Such is The carrier Z) contains-inareces's at the rear. the sliding block i, the top 7c of which. works,when raised, in the groove of the lock f, in which works also thetrigger-catch. The carrier b turns round the screw-bolt g t, which formsat the same time the fulcrum ofthe bellcrank lever c s. The pin of theshort arm c works throgh a slot in the side of the carrier b, ina grooveof the block t', which is allowed to rise and `fall. The extractor oisnot altered at all in this construction, but is that of the old gun. Ido not bind myself to one form of the parts.

I claim as my inventionl; In a repeating nre-arm with cylinder-lock, thelongitudinally-sliding extractor o, having shoulders 1o q, incombination with the vertically-sliding block i, havingatop piece, k,and with the carrier b, substantially as shown and described.

2. In a repeating fire-arm with cylinder-lock, the bell-crank lever s,in combination with the vertically-sliding piece t' .76, moving up anddown in ways on the carrier adapted to move it into and out ofengagement with the shoulders p q, carried on the sliding lock f, as shown and described.

3. 'Ihe offset x formed on the chamber C, in combination with thesliding piece t' working on the side of the carrier, and with saidcarrier b adapted to lock the latter in its eleva-ted position bythedepression of the slide-piece i, ,as herein specified.

4. The spring e, furnished with the swells n1, and a and head d. incombination with the carrier b of a repeating fire-arm and with thebreech piece orlock f, as shown and described, and adapted for jointoperation, substantially as set forth.

5. The carrierb, governed bythe slide-block t', acting in the rear endthereof to tilt it, and havingthe top piece, 7.4, on which act theshoulders 1) q of the extractor o, or the equivalent devices ofthelockf, in combination with said lock f and with the spring e, with itsswells m n andy head d, all working together 'as described, and for thepurpose explained.

This specification signed by me this 5th day of February, lSSl.
